That was the issue, the :file reference needed to be on the line above. Thanks.

Hi John,

I would actually like to plot different lines per distance, each
that correlate to a date and elapsed-time (x and y axis respectively).
I get an error with the :file notation, though I read that in a sample
babel gnuplot example for generating graphs of commit history on the
org-mode git repository. I tried to reference the variable data without
the quotes and $ sign without any success. I will continue to fiddle
with it, I am new to gnuplot.

AFAIK, you can't break source code header argument lines across
multiple lines. Is that how you actually have it in your
org file?

#+begin_src gnuplot :var data=sessions
:file org-running.png :exports both
set title "Running Stats"
set auto x
set style data histogram
set style fill solid border -1
set boxwidth .9
set xlabel "Date"
set ylabel "Time"
plot "$data" using 1:2:3 notitle
#+end_src
